OIL-BURNER.

SPECIFICATION forming part of Letters Patent N o. 741,820, dated October20, 1903.

Application filed March 30,1903.

To all whom it may concern.-

Be it known that I, ALEXANDER JOHN OBRIEN, a citizen of the UnitedStates, residing at Beloit, in the county of Rock and State ofWisconsin, have invented certain new and useful Improvements inOil-Burners; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in hydrocarbon or oil burners.

The object is to provide a burner of this character which can be usedfor generating heat in hot-air furnaces, stoves, hot-water heaters,steam-boilers, and the like.

Another object is to provide improved means for heating the oil,removing the impurities, and converting the same into gas beforereaching the burners. Y

With these and other objects in View the invention consists of certainnovel features of construction, combination, and arrangement of parts,as will be more fully described, and particularly pointed outin theappended claims.

In the drawings, Figure l is a side view of the burner complete. Fig. 2is avertical longitudinal sectional view of the same. Fig. 8 is across-sectional View; and Fig. 4 is a View similar toFig. l, showing theburner inclosed in a casing or boX.

In the drawings, l denotes the oil-tank; 2, lthe oil-feed pipe, providedwith a valve 3 for regulating the flow of oil from the tank.

4 denotes the generator or retort, which has a fiat top and a verticalside and is cut away on one side on a curve to form a depending flange 8and an overhanging shoul- The retort has a longitudinal retortpassageformed in its upper portion arranged for the connection of the feed orsupply pipe at one end. A vapor-discharge tube lO is connected to theother end of the said pas` sage and ends in the horizontally-disposedpipe 9, arranged beside the depending flange and beneath the overhangingshoulder of the retort or generator and provided with a series of burneropenings or jets l2, which are arranged to discharge the gas or vaporagainst the curved portion of the retort. The same Serial No. 150,217.(No model.)

beingignited effects the thorough heating of the retort audits passage,as will be understood. The depending tiange Son the rear side of theretort or generator forms a shield or wall for the purpose hereinafterystated.

Beneath the burner-tube is arranged a driptrough 13, into which a smallquantity of oil may be run and lighted to start the generator. In Fig. 4the generator and burner-pipe are shown inclosed in a sheet-metal box orcasingle, open at its upper side, and in the conical shaped bottomthereof is formed a centrally-disposed opening l5, surrounded by aiixed, downwardlyextending, and flaring iiange 16, an annular series ofholesl also being formed through the bottom, as shown.

`The purpose of the casing is to create a suction of air into its lowerend and discharge the same in a blast at its upper open end.

The construction of the'generator, as herein shown, with a rear shieldor wall is for the purpose of deliecting or directing the flame up andaround the body of the same to constantly heat the oil-passage thereinand to prevent the draft through furnace or stove from blowing the flamefrom the burners away from contact with the generator. The carbon liningin the passage 6 has a catalytic action on the oil in its conversioninto vapor and being porous acts as a sieve to catch the impurities andprevents clogging up of the burner-pipe.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation ot the inventionwill be readily understood without re` qniring a more extendedexplanation.

Various changes in form, proportion, and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention'. i

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. In combination with a burner, a retort having a passage formedtherein for Vaporizing oil to be supplied to the burner, and alining-tube of porous carbon in said passage, substantially asdescribed.

2. A horizontally-arranged retort having a ICO Vof burner-openingsarranged to discharge against the curved portion of the retort,substantially as described.

3. A horizontally-arranged retort having a dat top and Vertical side,and cut away on one side'on a curve, to form a depending flange portion,and an overhanging shoulder, having a retort-passage formed in its upperportion arranged for the connection of a supplypipe at'one end, and avapor-discharge tube connected to the other end of said passage andending in a horizontal pipe arranged beside said depending ange andbeneath the overhanging shoulder andv provided with a series ofburner-openings arranged to discharge against the curved portion of Vtheretort, in combination with a casing inclosing said retort anddischarge-tube and provided with a downwardly-extended neck portionhaving air-inlet openings therein, substantially as described.

ln testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
